I am working on a Desktop Computer with AMD Athlon 64 Processor 3500+, 2.20 GHz and 768 MB Ram. I have 2 identical HDD SATA, each with 1 TB, on one of them WinXP SP2 in Englisch is installed. This version runs fine, no complaints. For some programmes, which require SP3, I purchased a German version and installed it on the second HDD. Whenever, the file manager has to run, the programme is extremely slow, stops or force me to shut it down. ACDSee cannot be used at all. What can be the reason?
